intro and help with numb hands-weight distribution
Hello everyone, my name is Alex from Portugal, been riding for more than 30 years consistently (now 48yo) both MTB and road. This is a video of me riding my specialized Aethos, size 56. I'm 6ft tall. I don't know but looking at the images doesn't seem to be anything wrong (maybe heel drop although saddle is at the right height). Tried multiple saddle positions,Handlebar widths and stem lenghts. At the moment using a 20 mm setback Seat Post and a 90mm stem. The saddle is a selle SMP because it's the one that gives me more support. with pretty much any other saddle (levelled or nose slightly pointing up), It feels like I'm falling onto the handlebars. it's like having no support. And even with the SMP saddle, I still have a lot of pressure on my hands and this is my main concern and why I'm seeking advice. tried also different crank lenghths and the shorter, the worse it gets. Now with 172.5mm. Cleats are all the way back (closer to the heel). Main issue is numb hands and very tired hands after just a few minutes of riding. And if I'm pushing harder it's even sooner. It feels like the majority of my weight is being supported by my hands. I've seen The Bike Fit Academy's video on YouTube which mentions the right position for the saddle to be in (so that the weight is well distributed) but I don't know to calculate or find that position. Any help is highly appreciated- thanks

Just from my experience I’d say finding the balanced position has to be the first step. My bike has a moderately aggressive seat tube angle and came with a 0 setback seatpost. I had bad hand numbness for while until I watched some videos. I bought a seatpost with a 25mm setback and pushed my saddle most of the way back on the rails - problem solved. Good luck anyway. PS If you feel more comfortable with the hoods tilted up, it might be a sign that your reach is too long but then again it might be perfectly fine for you.

That’s a tough one. I can see that you have a setback seat post, although not quite as much setback as me. I can also see you are stretched out quite low already to reach the hoods. One other thing occurred to me, which is levelling the saddle. My saddle is also curved like yours, not quite as much. I made the mistake of levelling from the back of the saddle to the nose and kept feeling like I was rolling down it. In fact I actually needed the widest part near the back of the saddle to be level, which meant the nose was up. Looked odd but much more comfortable and when I read a bit more, turns out to be the ‘correct’ way. Just an idea. I hope someone who knows more than me comes along with some better advice and you get it sorted. Nice looking bike by the way 👍
Saddles - Sorted ✅
Thanks to everyone who joined the webinar on: Why Some Saddles Work For Some Riders (And Fail For Others) We discussed: - flat vs curved saddles - V-shaped vs T-shaped designs - rider movement patterns - pelvic posture - and why the “best saddle” is usually the one that interacts best with you, not someone else. Hopefully it helped clear up why saddle choice is much more about rider interaction than simply finding the most popular option 👍 Next up: 🚨 FREE Bike Fit Masterclass🗓 Friday 29th May - 4pm BST Why Your Hands Go Numb On The Bike We’ll be digging into: - hand numbness - upper body load - support vs pressure - and why cockpit length often gets blamed too quickly 👀

I just had a chance to watch this absolutely brilliant video. Like many I’ve gradually absorbed bits of knowledge about saddles over the years. If only the info in this video was widely available in such a clear way - I can’t understand why the saddle manufacturers don’t explain this stuff, let alone the more well known YouTube channel networks (you know who I mean). The whole saddle width/hip rotation thing was new to me but makes perfect sense. By a bit of luck and judgement I think my current V shaped curved saddle is about right for me - now I know why. More importantly, I now understand it’s OK to roll forward a little on the saddle to the narrower part if I go into a bit more of a tuck, rather than tying myself in knots trying to keep my sit bones planted in the well of the saddle during those stages of the ride (I have reasonable hip flexibility). Thanks again for a brilliant video - I signed up for the paid membership now.
Saddle height - the lower limit
There's loads of talk about saddle height and why we shouldn't run our saddles too high. But what about the other end of the spectrum - going lower? I can't really see much solid rationale (in terms of performance) for why I can't reduce my saddle height but still be able to produce the same power. As far as I'm aware, the common approach by bike fitters to setting saddle height (and I'm simplifying here) is to start with a low saddle, gradually raise the saddle to the point where foot instability or pelvis instability is starting to appear, then go down 3-5mm. This seems to be based on the belief that a higher saddle is better, up to the point where instabilities creep in. What are the issues or dangers to running saddle height too low?

When I tried too low, it made my knees hurt. Turns out if your knee angle is too acute, it puts a lot of strain on the structures around the knee when you start on the power phase of the pedal stroke. Or at least it did for me.
Saddle tilt
What is the best way and device to measure tilt? I measure the front half of the saddle (Selle San Marco 3dfx) with the app saddle adjust on my iPhone but as it has a camera bump the readings are off. Any other techniques?

I thought we were supposed to measure only the area where we make contact with the saddle, roughly the dip where the widest part is? Unless your saddle is completely flat. (I only ask because I’m still adjusting mine trying to get it right).
